How it works

Set up once in your admin. Works automatically on your storefront.

01

Define your levels

Create the criteria your customers use to narrow down products — Brand, Model, Year, Size, Material, or anything custom. Each level cascades into the next.

02

Map products to terms

Assign which products are compatible with which combinations. Import thousands of rows via CSV in seconds, or map manually for smaller catalogs.

03

Add the widget to your theme

Drop the finder block anywhere in your theme using the Theme Editor — no code required. Works with any Shopify 2.0 theme out of the box.

04

Customers find what fits

Shoppers make their selections and instantly see only the products that are compatible. Fewer returns, more confidence, higher conversion.

Everything you need

A complete compatibility system, not just a widget.

⬇️

Finder Widget

Cascading dropdowns on any page — homepage, collection, product, or a dedicated results page.

Compatibility Checker

Show a 'Compatible' or 'Not Compatible' badge on product pages based on the customer's current selection.

📋

Compatible With List

Show a full list of what each product is compatible with, right on the product page.

🔖

Saved Searches

Logged-in customers can save their vehicle or criteria and get instant results on return visits.

📌

Sticky Banner

A persistent banner that remembers the customer's selection across pages so they never lose context.

📤

CSV Import

Import thousands of product-to-term mappings in one go. Supports range expansion (2018–2024 becomes individual years automatically).

👻

Ghost Scan

Automatically detect and remove orphaned mappings where the Shopify product has been deleted.

🌐

Universal Products

Mark certain products as universal — they appear in every search result regardless of the selection made.
